While it isn't among the list of resorts you listed, I would also suggest you take a look at Grand Case Beach Club. It is a favorite among many who visit the island and has the advantages of:
- being close to Orient Beach where you say you spend most of your time
- having its own beach with nice sand and almost no waves
- having the Sunset Cafe which offers good breakfasts, lunch and dinner as well as a nice bar for watching sunset
- being an easy walk to the town of Grand Case and some of the best restaurants on the island
- being a small, friendly and intimate hotel and not crowded like the Simpson Bay properties can be

You may want to look into it. Good luck.
